Patented Nov. 18, 1952 UNITED STATES PATENT OFFICE` 8 Claims.

This invention relates to tamperproof coin boxes for use in vending machines, fare boxes, telephone pay stations, coin-operated turnstiles, and the like, and has for its principal object the provision of a new and improved device of this kind.

It is a main object of the invention to provide a coin box that is locked and conditioned for insertion in a vending machine by an ofcial at the office, prior to delivery to the collector who inserts it in the machine out in the eld, and which, when once inserted in the machine, is locked therein and on removal therefrom is automatically locked in tamperproof position.

Another object of the invention is to provide a locked, removable coin box that can be inserted in and removed from a vending machine in locked condition, without the use of keys or tools by the collector.

Another object of the invention is to provide a coin box which is self-locking in tamperproof condition and which must complete the operation of locking itself in such condition before it can be removed from the vending machine.

Still another object of the invention is to provide a simple, sturdy mechanism that can be manufactured at low cost, without sacricing quality, and can be maintained in proper operating condition economically.

Further objects of the invention not specifically mentioned herein will be apparent from the description and claims which follow, reference being had to the accompanying drawings in which a preferred embodiment of the invention is shown by way of example and in which:

Fig. 1 is an elevational view of a portion of a vending machine showing the coin box in operating position in a vending machine;

Fig. 2 is a cross-sectional view taken substantially along the line 2-2 of Fig. 1, looking in thel direction of the arrows;

Fig. 3 is a plan View of Fig. 1;

Fig. 4 is a cross-sectional view along the line 4-4 of Fig. 2, looking in the direction of the arrows and showing the bolt in triggered position;

Fig. 5 is a view similar to Fig. 4, showing the bolt in the position assumed when the box is in operative position in the machine; and

Fig. 6 is a View similar to Fig. 4, showing the bolt locked in tamperproof position.

Coin-operated vending machines, fare boxes, telephone pay stations, turnstiles, and the like, usually consist of a casing within which is a chute through which the coins pass into a box or receptacle from which they are removed by the collector when the machine is being serviced. Frequently the coin receptacles are open-top boxes, usually metal, and in which loose coins are contained.

Machines of this type are used in varying locations and it has been found that the practice of dumping the loose coins from the coin box into a bag or Satchel results in the lossof many coins and, in addition, in certain instances, pilfering of the coins by the collector has been practiced.

In the prior art of which I am aware, numerous attempts have been made to provide a coin box which can be locked by a suitable ocial of the company and delivered to the collector for insertion in the vending machine, the box after` being., lled or partially filled with coins j bein'gfremoved from the machine and returned to the. company ofce where it is unlocked and its con# tents removed by proper ofcials, a second box being installed in the vending machine mean- While.

Such prior art devices, while an improvement over the open coin receptacle, nevertheless have been subject to the criticism that they were not .V entirely tamperproof, and it has been possible for dishonest employees to pilier coins from the boxes l Without detection.

The present invention provides a locked box which is conditioned or triggered by a proper company oilicial for insertion in the vending ma-A through which coins enter the box willvbe auto` matically moved into slot-closing position and locked therein before the boxcan be freed for removal from the vending machine. When come pletely removed from the machine, the coin box is completely locked and coins cannot be removed from it surreptitiously without mutilation of the box, a practice seldom indulged in because of the ease of detection. The box and its. contents are delivered to proper oicials who empty the box and re-trigger it f or re-insertion in a machine.

In the drawings, a vending machine is fragmentarily shown and consists of a casing have. ing a back wall-I, upon which is mounted a chute 2 through which coins enter the removable box generally shown at 3. Mounted upon the sideA walls 4 and 5 of the casing are anges 4i5 which serve to lsupport the removable coin box in thecasing, as will presently appear.

Also mounted upon the side walls 4 and 5 are star wheels 'I rotatably supported upon suitable pivots 8 and capable of rotating thereupon. Also mounted on the side wall is a pawl 9 pressed against the star wheel by a suitable spring I and serving to limit movement of the star wheel to rotation in one direction. As shown in the drawings, the star wheel, pawl and spring are mounted as a unit in a suitable casing Il which can be attached to the side walls 4 and 5 of existing machines by suitable means such as screws I2.

The coin box consists of an open-top receptacle I3 and a cover I4, the receptacle being perforated near the top to receive lugs I by which one edge of the cover is secured to the box. The cover carries a suitable locking device I6 on the edge opposite the lugs I5 and through the operation of which the cover` is securely locked on the box.

Preferably the cover is a ilanged cover and fits down over the outside of the box I3, as shown, the lower edge of the flange engaging flanges 6, thereby to support the coin box in the machine.

Mounted upon the underside of the top of the cover is a bolt, indicated generally at 2 6, consisting of three plates 2|, 22 and 23, the outer ones w 2| and 23 of which are permanently fastened together to form a guide for the center plate 22 which is movable with respect to the others.

All three plates contain an elongated central slot 24 through which are extended collared screws 25 by which the bolt is mounted upon the cover for limited longitudinal translatory movement with respect thereto.

The plate 23 contains elongated slots 2t through which rare projected pins 21 carried by the central plate 22 to guide and limit the movement of the plate 22 with respect to the other plates.

Plates 2|, 22 and 23 each contain a generally V-shaped notch 3Q, and the notches of the Ythree plates are aligned when the plate 22 is moved with respect to plate 23 to position pins 21 in the ends of slots 26 nearest the notch 36 in plate 23, as shown in Fig. .4. Plate 22 carries at one end a nger 3I by which it may be moved with respect to the other plates Mounted upon the cover is a `,pawl 32 which is pressed by a suitable .spring 33 into the aligned notches 3i), thereby .to hold the bolt in triggered position. It will be noted in Fig. 4 that whenthe bolt is in triggered position, the end .34 of the bolt is spaced inwardly from the outer edge of the cover.

Mounted upon Vthe underside of the coverby suitable brackets 35 are pins 33 which extend through the Iianges of the cover and are disposed at right angles to the longitudinal axis of lthe bolt 26. Suitablesprings 3l encircle these pins 36 and are tensio-ned to move the pins inwardly toward the bolt.

Each of the plates 2|,.22 and 23 also contains a generally rectangular slot. 38, which slotsVwhen the slidable plate 22 is in the position shown in Fig. 5, that is, with the pins 2 at the ends of the slots 26 farthest from notch 33 in plate '23, 'form mortises leading into the opposite edges of the bolt. The movable plate 22 contains .cam surfaces39 arranged so that as the plate 22 is moved into the position shown in Fig. 4, pins 35 will be l 4 Spring 4i, extending between one of the pins 2l, carried by plate 22 and a suitable pin on plate 23, is tensioned to aid this movement of the plate.

When the cover is locked on the box I3 with the bolt 26 in the position shown in Fig. 4, the box is ready for insertion in the machine. As the box is pushed inwardly of the machine, pins 36 engage the star wheels 'l and rotate these wheels. The end 32 of the bolt engages the chute 2, and as the coin box is moved into position the bolt 23 is moved into the position shown in Fig. 5.

Mounted within the cover and engaging the nger 3i is a spring 4Q tensioned to move the bolt to register the end 3ft thereof with the flange on the cover, as seen in Fig. 6. As the outer end 33 of the bolt engages the chute, further movement of the coin box forces the bolt inwardly of the cover and spring 43 moves the plate 22 so as to position pins 2i at the ends of the slots 25 `nearest the end 33 of the bolt, as shown in Fig. 5. Spring is tensioned by this movement of the plate 22; however, since the spring 4I is weaker than the spring 2Q, plate 22 remains in the position shown in Fig. 5, l

This movement of the plate 22 moves the notch 33 in the plate 22 out of registration with `the notches 35 in the plates 2i and 23, as will be seen in Fig. 5. This action moves the pawl 32 against the tension of spring 33 and into alignment with the edge of the bolt. This movement of the plate 22 also moves the cams 39 out of registration with the slots in the other plates, thereby opening the mortises 33 for future use. The bolt and coin box are now in the position in which they are shcwn in Figs. 2 and 5, that is in the machine in readiness for the reception of coins.

When it is desired to remove the coinV box from the machine, the box is Vslid forwardly thereof, that is, to the right, as seen in Fig. 2. It will be noted that the pin 36 has moved past a tooth on the star Wheel 'I and that there is an appreciable distance between the pin 36 and the lowermost tooth on the star Wheel, so that the box can be moved a short distance while the pins 36 are in extended position. As this movement is carried out, the edge of the cover adjacent end 34 of the bolt, is moved into alignment with the edge of the chute 2, as shown in Fig. 6. Spring 46, being tensioned to urge the bolt 23 towards this edge of the cover, maintains the edge 34 of thebolt in engagement with the chute 2 and during this movement the bolt ,moves from the position shown in Fig. 5 into the position shown in Fig. 6. When the edge 34 of the bolt is aligned with the lowermost edge of the cover, mortises 38 are in alignment with the pins 36, and springs 3l move the pins 3.6 into the mortises thereby locking the bolt in the position in which it is shown in Fig. 6. In this position the slot in the cover into which the coin chute 2 iits, is completely closed. Movement of the pins 36 into the mortisesretracts the projecting ends `of these pins into alignment with the flanges on the cover. This vretraction of the pins moves them outof .en-

gagement with the star wheel l, thereby freeing the coin box so as to permit it to be removed from the machine. I

So long as the pins 35 remain in the mortises, the bolt 20 cannot be moved to open the slot, and consequently coins cannot be extracted from the coin box. the pins 36 with the anges of the cover make springs 31 next to impossible.

Alignment of the outer ends of Y It will be apparent that movement of the plate 22 with respect tothe other plates will cam the pins outwardly, and if the plate 22 were exposed it would be relatively simple to tamper with a locked box. As will be seen best in Fig. 2, the end of the plate 22 adjacent the end 34 of the bolt is not exposed to view, but rather a filler 44 extends between the plates 2| and 23, thereby guarding the movable plate 22 so that it cannot be moved from the outside of the cover.

In the drawings, the front cover of the vending machine, `which ts over and conceals the coin box and lstar wheel assemblies, has been.

omitted to avoid an unnecessary complication of the iigures.

The coin box of the present invention is possessed of many advantages. It can be manufactured asa strong, sturdy unit economically. If desired, the cover and box may both be casehardened, thereby to make tampering with the box more diiicult. When triggered and locked by a proper oicial and delivered to the collector for insertion in the machine, the bolt is set so that it is impossible to put the coin box in the machine Without releasing the trigger, thereby to set the bolt for automatic closure of the slot in the box when removal of the box from the machine is attempted.

While I have chosen to illustrate my invention by showing and describing a preferred embodiment of it, I have done so by way of example only, as there are many modifications and adaptations which can be made by one skilled in the art Within the teachings of the invention.
